A Gas Safety Certificate, also known as a CP12 or CP42 (also known as a commercial gas safety certificate and a residential gas safety certificate), is an official document issued after a gas safety inspection. It confirms that gas appliances, pipework, flues, and safety controls in a property are safe to use at the time of inspection.
The certificate includes details of the property, the appliances checked, the results of the inspection, and the Gas Safe engineer who carried out the work. In the UK, this certificate is valid for 12 months.
Gas safety checks are essential in London because gas faults are often invisible. Problems such as poor ventilation or hidden leaks can become life-threatening if ignored.
Professional CP42 gas safety checks for restaurants, commercial kitchens, and business premises.
Certified Gas Safe engineers providing fast, reliable CP12 inspections for homes and rental properties.
Yes. Under UK law, a Gas Safety Certificate is a legal requirement for landlords, estate agents, property managers, tenants, home buyers, and sellers in London.
Landlords must ensure that all gas appliances and pipework provided in a rental property are checked every year by a Gas Safe registered engineer. A valid certificate must be given to tenants before they move in, and existing tenants must receive a copy within 28 days of the inspection.
Homeowners are not legally required to hold a Gas Safety Certificate unless they rent out their property. However, many homeowners still choose to have a gas safety check for peace of mind and safety.
A Gas Safety Certificate is required for any landlord renting out a property with gas appliances. This includes private landlords, letting agents, and property management companies.
It is also required for HMOs, blocks of flats with shared gas systems, and commercial premises such as shops, offices, restaurants, and industrial units.
London properties often include older buildings, basement flats, and shared pipework. These factors increase gas safety risks, which makes regular inspection even more important.
A Landlord Gas Safety Certificate, commonly called a CP12, is issued after a successful inspection of gas appliances and installations in a rental property.
As a landlord, you are legally responsible for arranging this inspection every 12 months. Failing to do so can result in fines, enforcement notices, invalid insurance, and serious legal consequences.
Furthermore, at Safety Spectrum London, we conduct CP12 inspections for landlords in London. The timetables and access difficulties associated with letting property, as well as compliance documentation for the council, are things that we understand and take into consideration.
Commercial properties require a Commercial Gas Safety Certificate, often referred to as a CP42. This applies to businesses that use gas appliances or have gas installations within their premises.
Commercial gas safety inspections are more complex due to higher gas usage, multiple appliances, and increased risk levels. Restaurants, takeaways, hotels, factories, and office buildings all fall under this requirement.
Our engineers are experienced in commercial environments and understand the importance of minimal disruption while maintaining full legal compliance.

Commercial Gas Safety Certificate in London
During a gas safety inspection, the engineer checks all relevant gas appliances and installations to ensure they are operating safely.
This includes the gas appliances like boilers, cookers, and gas fires as well as gas pipework, ventilation systems, flues, and the emergency control valve at the gas meter.
A tightness test is carried out to detect gas leaks, and ventilation is assessed to prevent carbon monoxide buildup. If any appliance is unsafe, it is clearly recorded in the report with advice on next steps.
How Long Does a Gas Safety Certificate Last?
The Gas Safety Certificate is valid for 12 months from the time of inspection.
The landlord is required to renew it every year even if there is no change in appliances. In fact, it is always advisable to plan an inspection before the certificate expires.
